超厚大体积混凝土温度控制与现场监测

Controlling and In-site Monitoring Temperature in Ultra Thick Mass Concrete

结合工程实际,分别从材料、施工措施和现场温度控制等几个方面对大体积混凝土基础裂缝控制的方法进行了论叙。对大体积混凝土基础进行了温度预测计算和现场测温,并对预测结果和实测结果进行了比较分析,混凝土温控监测数据表明采取的温度预测控制方法是有效的,其结果将为其它大体积混凝土的施工提供有益参考。

Combined with practical engineering, monitoring means on the crack of mass concrete are discussed. The monitoring means include material measures, construction measures and temperature control measures. The predication on temperature of mass concrete foundation is calculated and the temperature is tested. The results of predicting and testing are compared. According to the calculation temperature and date of monitoring, it indicated that the monitoring methods are effective in the construction site and draws a conclusion by field temperature control and measurement of mass concrete, which to offer valuable reference for other mass concrete construction.
